American Memory is a gateway to the Library of Congress’s digitized American historical materials, organized into more than 100 thematic collections. Original formats include manuscripts, prints, photographs, posters, maps, sound recordings, motion pictures, books, pamphlets, and sheet music. Each collection provides explanatory features to make the materials easy to find, use, and understand. Collections may be browsed individually, searched individually (including full-text searching for many written items), or searched across multiple collections. 1400s-present.

Artemis Primary Sources indexes citations and full text from Gale's Eighteenth and Nineteenth Century digitized collections Sabin Americana, and The Making of the Modern World, including books, manuscripts, newspapers, maps, and early photographs.
